Color and TOC removal from pulp and paper wastes by ultrafiltration
… less than 5 color units and less than 5 mg/L TOC (99% and 97% removal respectively). The data also indicate that biotreatment of the wastes prior to ultrafiltration removes the smaller molecular weight organic compounds, making ultrafiltration more effective. Pretreatment by pH adjustment and …

Application of Ozone in Dissolved Air Flotation (DAF) for Enhanced Removal of TOC and Suspended Solids in Pulp and Paper Wastewaters
Pulp and paper mills are one of the top consumers of water related to industrial manufacturing, which ultimately leads to a large volume of heavily contaminated wastewater. This discharged effluent can have a harmful effect on the receiving aquatic environment and cause further ramifications …

Exploring poor outcomes from quality assurance programs – An analysis based around the concept of Mechanisms and The Theory of Constraints (TOC) Thinking Process (TP)
… new feature within the Theory of Constraints (TOC) - the Strategy and Tactic (S&T) tree - was used. The thesis demonstrates how combining the S&T tree with Treacy and Wiersema’s (1993) strategic choices has important outcomes for QAP. The aim of this thesis is to explain the anomalous outcomes …

Determination of thermo-optic coefficient for B2O3 and GeO2 co-doped optical silica fiber
… B2O3 and GeO2 on the thermo-optic coefficient (TOC) of silica optical fiber. This is important since understanding the contributions to the TOC by these constituents can provide insight into the way to lower the positive-valued TOC of SiO2, which is a potential method to decrease the influence …

Using Theory of Change to design and evaluate complex mental health interventions in low and middle income countries: the case of PRIME
… to evaluation such as Theory of Change (ToC) (Anderson 2008). De Silva, Breuer et al. (2014) have proposed that ToC may complement the MRC guidance on complex health interventions. Methods: This study explores how ToC can strengthen the design and evaluation of complex health …

Nutrient Sources and Transport in the Central Region of the Big Sioux River, South Dakota
… nitrogen (TON), and total organic carbon (TOC) were measured from November 9, 1971 to November 8, 1972 on the Big Sioux River, Six Mile-North Deer Creek, and Drainage M. The Big Sioux River transported 418,640 x 10 3 m3 of water, 776,880 kg TP, 599,590 kg TON, and 5,419,580 kg TOC during …

Total Organic Carbon and Clay Estimation in Shale Reservoirs Using Automatic Machine Learning
High total organic carbon (TOC) and low clay content are two criteria to identify the "sweet spots" in shale gas plays. Recently, machine learning has been proved to be effective to estimate TOC and clay from well loggings. The remaining questions are what algorithm we should choose in the first …

Origin and Transport of Nutrients in the Upper Big Sioux River, South Dakota
… kg, and 61,600 kg of the total organic carbon (TOC), total organic nitrogen (TON), and total phosphate (TP), respectively. This amounted to 852, 71, and60 kg/km2 per year of TOC, TON, and TP, respectively. The city of Watertown (Segment 2) had a drainage area of 7.5 km2. This segment contributed …

Factors Affecting Mobility of Copper in Soil-Water Matrices
… factors that may affect this mobility process; TOC, dryness and its temperature cycle and water content of the soil were selected for study. These factors were investigated in both batch and continuous flow (column) processes. Copper mobility through soil columns was associated with TOC …
